We have defined Lagrange stability and input-to-state stability for nonlinear systems on manifolds. Furthermore, we have presented necessary and sufficient conditions for stability by using continuous positive definite proper functions. We have designed an ISS-control Lyapunov function and an input-to-state stabilizing controller for an obstacle avoidance problem of a mobile robot. Then, we have confirmed the effectiveness of the proposed controller by computer simulation. We have proposed a sample input-to-state stabilizing controller for general nonlinear systems on manifolds.
